The D-50 was Roland’s flagship and most popular synthesizer in 1980s. It employed so-called “linear arithmetic synthesis”, which combined sampled (PCM) transients with a variation on subtractive synthesis, including resonant low-pass filters. It also had a joystick. It remains a popular instrument for its pads and other characteristic sounds. Roland released a re-creation of it for their “Boutique” line, the D-05.
